Abstract

Stability parameters in 33 oat genotypes were studied to obtain information on the magnitude and nature of G x E interactions and stability for forage yield. These genotypes evaluated under three environments i.e. E1 (2006–07), E2 (2007–08) and E3 (2008–09), depicted significant interaction with the environments for both green fodder and dry matter yields. OS 7, a high yielding genotype and responsive to favourable environment, was found to be the most unstable one for both the characters. The high yielding genotypes which were stable over environments and responsive to favourable conditions included JHO-851, OS-297 and OS 293. The genotypes OS 311, OS 315, JHO 2000-6 and JHO 2000-2 were high yielding, responsive to poor environment and least deviating from regression while UPO 271 was found to be high yielding, responsive to average environment and stable one.
